Description

Technical Field

[0001] This utility model relates to the technical field of artificial quartz stone slab production equipment, specifically to an artificial quartz stone slab laminating machine. Background Technology

[0002] Panel lamination refers to a decorative material made by bonding polyester film as adhesive to the surface of substrates such as particleboard, MDF, plywood, and quartz stone slabs through a hot-pressing process. Its function is to enhance the hardness and stability of the panel, making the substrate more robust and stable, and preventing deformation and cracking. The polyester film base of the panel lamination effectively prevents surface defects and bubbles from appearing on the substrate, resulting in a smoother and more aesthetically pleasing surface. Simultaneously, the lamination also protects the panel surface, extending its service life.

[0003] The existing artificial quartz stone slab laminating machine has the following shortcomings: First, the laminating roller is installed using a rigid connection, so the laminating roller is not tightly attached to the surface of the artificial quartz stone slab, which easily leads to air bubbles forming on the film and the surface of the artificial quartz stone slab; Second, the film is laminated on one side and unwound on the film reel on the other side by the motor. Since the laminating speed and unwinding speed are sometimes not completely consistent during the laminating process, the film is either too loose or too tight during the unwinding process. If it is too tight, it will damage the film, and if it is too loose, it will affect the laminating effect. Utility Model Content

[0004] The purpose of this invention is to provide a laminating machine for artificial quartz stone slabs that can adjust the tightness of the exported film in real time.

[0005] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:

[0006] A laminating machine for artificial quartz stone slabs includes a frame, a slab conveyor belt, a film reel, an unwinding motor, a film tension adjustment device, a film correction mechanism, a laminating roller, and a film cutting device. The slab conveyor belt passes through the frame. The film reel, film tension adjustment device, film correction mechanism, laminating roller, and film cutting device are mounted on the frame. The film on the film reel passes through the film tension adjustment device, film correction mechanism, and laminating roller. The unwinding motor drives the film reel to rotate. The film tension adjustment device adjusts the film tension. The film correction mechanism prevents deviation during film conveying. The laminating roller applies the film to the surface of the artificial quartz stone slab on the slab conveyor belt. The film cutting device cuts the film after laminating the slab.

[0007] Furthermore, the laminar roller is installed at the lower end of the movable pressure rod, the upper end of the movable pressure rod is inserted into the slide tube, the upper end of the slide tube is closed, and a compression spring is provided between the end face inside the slide tube and the upper end of the movable pressure rod. The slide tube is fixed on the frame, and under the action of the compression spring, the laminar roller is pressed tightly against the surface of the artificial quartz stone slab on the slab conveyor belt.

[0008] Furthermore, the film tension adjustment device includes a machine base, a left guide roller, a gravity tension roller, a right guide roller, and a controller. The machine base is provided with a vertical slide groove, and the sliding shafts at both ends of the gravity tension roller are located in the vertical slide groove. An upper pressure sensor and a lower pressure sensor are respectively provided at the top and bottom of the vertical slide groove. The left and right guide rollers are installed on both sides of the machine base. The film passes over the left guide roller, the gravity tension roller, and the right guide roller, and the gravity tension roller is supported on the film. When the film tension is small, the gravity tension roller moves downward; when the film tension is large, the gravity tension roller moves upward. When the gravity tension roller moves downward, and the sliding shafts at both ends of the gravity tension roller press against the lower pressure sensor, the lower pressure sensor transmits information to the controller, and the controller reduces the speed of the unwinding motor. When the gravity tension roller moves upward, and the sliding shafts at both ends of the gravity tension roller press against the upper pressure sensor, the upper pressure sensor transmits information to the controller, and the controller increases the speed of the unwinding motor.

[0009] Furthermore, the film cutting device includes an electric push rod, a blade holder, and a long strip-shaped cutting blade. The long strip-shaped cutting blade is mounted on the blade holder, the blade holder is mounted on the lower end of the electric push rod, and the upper end of the electric push rod is fixed to the frame.

[0010] Furthermore, the film correction mechanism includes a roller frame, two guide rollers and two correction rollers, with the guide rollers and correction rollers arranged in a row on the roller frame and the two guide rollers located between the two correction rollers.

[0011] Furthermore, the correction roller includes a roller body, a correction cone, and a support shaft. The correction cone is frustum-shaped. The diameter of the small diameter end of the correction cone is equal to the diameter of the roller body, and the diameter of the large diameter end of the correction cone is greater than the diameter of the roller body. The two ends of the roller body are connected to the small diameter end of the correction cone, and the support shaft is connected to the large diameter end of the correction cone. The roller body, the correction cone, and the support shaft are on the same axis.

[0012] Furthermore, the support shaft is mounted on the roller frame via bearings.

[0013] Furthermore, the unwinding motor is a servo motor.

[0014] Furthermore, the elongated cutting blade is connected to the blade holder by screws.

[0015] The beneficial effects of this utility model are as follows:

[0016] In the applicant's artificial quartz stone slab laminating machine, the laminating roller is installed at the lower end of the movable pressure rod, changing the rigid installation of the laminating roller to an elastic installation. Under the action of the compression spring, the laminating roller is brought into close contact with the surface of the artificial quartz stone slab, effectively avoiding the formation of air bubbles between the film and the slab.

[0017] In the quartz slab laminating machine manufactured by the applicant, a film tension adjustment device has been added. When the film is loose, the gravity tension roller moves down and the sliding shaft presses against the pressure sensor, the controller reduces the speed of the unwinding motor to increase the film tension. Conversely, the controller increases the speed of the unwinding motor to reduce the film tension. This design not only avoids damage to the film due to excessive tension during the film export process, but also avoids affecting the laminating effect when the film is too loose during the export process.

[0018] The applicant's quartz stone slab laminating machine also has a thin film correction function and is easy to operate and safe and reliable. Attached Figure Description

[0027] To enable those skilled in the art to better understand the technical solution of this utility model, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments. It should be noted that, in the absence of conflict, the embodiments and features in the embodiments of this application can be combined with each other.

[0028] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper surface", "lower surface", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "forward", "reverse", "axial", "radial", "circumferential", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] like Figure 1 As shown, a laminating machine for artificial quartz stone slabs includes a frame 1, a slab conveyor belt 2, a film reel 3, an unwinding motor 4, a film tension adjustment device 7, a film correction mechanism 8, a laminating roller 5, and a film cutting device 6. The slab conveyor belt 2 passes through the frame 1. The film reel 3, the film tension adjustment device 7, the film correction mechanism 8, the laminating roller 5, and the film cutting device 6 are mounted on the frame 1. The film 9 on the film reel 3 passes through the film tension adjustment device 7, the film correction mechanism 8, and the laminating roller 5. The unwinding motor 4 drives the film reel 3 to rotate. The film tension adjustment device 7 adjusts the film tension. The film correction mechanism 8 prevents the film 9 from shifting during transport. The laminating roller 5 laminates the film 9 onto the surface of the artificial quartz stone slab 13 on the slab conveyor belt 2. The film cutting device 6 cuts the film after laminating the slab.

[0030] The laminating roller 5 is installed at the lower end of the movable pressure rod 10. The upper end of the movable pressure rod 10 is inserted into the slide tube 11, which is closed at the upper end. A compression spring 12 is provided between the inner end face of the slide tube 11 and the upper end of the movable pressure rod 10. The slide tube 11 is fixed to the frame 1. Under the action of the compression spring 12, the laminating roller 5 is pressed tightly against the surface of the artificial quartz stone slab 13 on the slab conveyor belt 2. Installing the laminating roller at the lower end of the movable pressure rod changes the rigid installation of the laminating roller to an elastic installation. Under the action of the compression spring, the laminating roller is in close contact with the surface of the artificial quartz stone slab, effectively preventing the formation of air bubbles between the film and the slab.

[0031] like Figure 2 , 3 As shown, the film tension adjustment device 7 includes a base 21, a left guide roller 16, a gravity tension roller 15, a right guide roller 14, and a controller 22. The base 21 has a vertical slide groove 17. The sliding shafts 20 at both ends of the gravity tension roller 15 are located in the vertical slide groove 17. An upper pressure sensor 19 and a lower pressure sensor 18 are respectively located at the top and bottom of the vertical slide groove 17. The left guide roller 16 and the right guide roller 14 are installed on both sides of the base 21. The film 9 passes over the left guide roller 16, the gravity tension roller 15, and the right guide roller 14, with the gravity tension roller 15 supporting the film 9. The gravity tension roller 15 supports the film 9; when the tension of the film 9 is small, the gravity tension roller 15 moves downward; when the tension of the film 9 is large, the gravity tension roller 15 moves upward. When the gravity tension roller 15 moves downward, the sliding shafts 20 at both ends of the gravity tension roller press against the lower pressure sensor 18, and the lower pressure sensor 18 transmits information to the controller 22, which then reduces the speed of the unwinding motor 4. When the gravity tension roller 15 moves upward, the sliding shafts 20 at both ends of the gravity tension roller press against the upper pressure sensor 19, and the upper pressure sensor 19 transmits information to the controller 22, which then increases the speed of the unwinding motor 4. The unwinding motor 4 is a servo motor. This embodiment adds a film tension adjustment device. When the film loosens, the gravity tension roller moves down and the sliding shaft presses against the pressure sensor, the controller reduces the speed of the unwinding motor to increase the film tension. Conversely, the controller increases the speed of the unwinding motor to reduce the film tension. This design not only avoids damage to the film due to excessive tension during the film unwinding process, but also avoids affecting the peritoneum effect when the film is too loose during the unwinding process.

[0032] like Figure 4 As shown, the film cutting device 6 includes an electric push rod 25, a blade holder 24, and a long strip-shaped cutting blade 23. The long strip-shaped cutting blade 23 is mounted on the blade holder 24, and the blade holder 24 is mounted on the lower end of the electric push rod 25. The upper end of the electric push rod 25 is fixed to the frame 1. The long strip-shaped cutting blade is connected to the blade holder by screws.

[0033] like Figure 5 ,6 As shown, the film correction mechanism 8 includes a roller frame 28, two guide rollers 27 and two correction rollers 26. The guide rollers 27 and correction rollers 26 are arranged in a row and installed on the roller frame 28, with the two guide rollers 27 located between the two correction rollers 26.

[0034] The corrective roller 26 includes a roller body 31, a corrective cone 30, and a support shaft 29. The corrective cone 30 is frustum-shaped, with the diameter of its small-diameter end equal to the diameter of the roller body 31, and the diameter of its large-diameter end greater than the diameter of the roller body 31. The small-diameter ends of the corrective cone 30 are connected to both ends of the roller body 31, and the support shaft 29 is connected to the large-diameter end of the corrective cone 30. The roller body 31, the corrective cone 30, and the support shaft 29 are all on the same axis. The support shaft 29 is mounted on a roller frame 28 via bearings. When the film deviates and shifts to one side of the roller frame 28, the diameter of the corrective cone 30 gradually increases from the inside out, generating an inward pushing force on the film, causing it to return to its original position and preventing further lateral deviation.

[0035] Furthermore, those skilled in the art can combine and integrate the different embodiments or examples described herein, as well as the features of those different embodiments or examples, without contradiction. Although embodiments of the present invention have been shown and described above, it is understood that the above embodiments are exemplary and should not be construed as limiting the present invention. Those skilled in the art can make changes, modifications, substitutions, and variations to the above embodiments within the scope of the present invention.
